A dramatic, exotic looking evergreen shrub/perennial. In the right place, this is a great looking plant. It makes a good focal point in a border. It's also tough as nails.

Here, the evergreen foliage looks good into January, but heavy snow leaves it looking ragged from late winter till the new growth covers it in late spring. The leaves are softer than with most yuccas, and the hard points on the tips aren't very dangerous except perhaps to the eyes.

Though this is a full-sun plant in nature, it can perform well with less sun than is generally believed. I rescued a tiny single rosette and planted it where it gets sun only after about 2PM, and in single year it got big and bloomed. I often see this species doing well in moderate shade under trees.

... read more> In flower, this plant reaches 6 feet tall. The flowers are very beautiful, but they often get chewed up shortly after they open by a little beetle (Carpophilus melanopterus). Each flower only lasts a couple of days, but they open in succession over a two-week period. I cut the flower stems down when flowering is finished, and I cut back further when the foliage starts to fade. Individual rosettes die after flowering, but they always leave more pups before dying.

Needs only a few hours of sun and good drainage. Does well in low-nutrient sandy soils, and even in pure sand.

I planted a single Yucca in Madison, WI (zone 5) five years ago this summer, and always wondered why it never flowered. I thought it might be because of too much rain, pewny summers that were too cool and moist, not enough sun, overly harsh winters, etc. I never experienced the problems or issues that posters farthur south did regarding out of control behavior. I even wondered if the harsh Upper Midwest winters, cold Springs and early Falls played a roll. Add to that, a long, deep snow cover for many months and I wasn't too positive if my Yucca was all that happy, since it's leaves got weighed down by snow every Winter and looked shabby come Spring (yet it always sprung back in Summer). But what gave me hope that my yucca would some day bloom was to that I had seen other yuccas in Southern... read more Wisconsin bloom, so I knew it could be done. And this year was the year. I was sure that last summer, year 4, with several hundred degree days, drought, many 90s, etc. would be the year. But it wasn't meant to be. But this very wet and up until recently, cool summer, I got blooms!! And interestingly, I had multiple stalks. Aparently I hadn't been paying attention, the single yucca I had planted had sent up pups adjacent to it, and from a distance it looked like one big yucca, that had just been gaining in size. Well, three differet yuccas bloomed this summer, year 5. There are several other ones that must be the pups of those as well, I am hopeful they have grown in staggard years so I will have anual blooms.

My conclusion for other northern gardeners with this plant is that it finds strength in numbers, it will slowly grow, spread and establish itself...and it spends it's energy in this way before it flowers (and dies back to be replaced by more pups). Maybe the process takes longer at our latitude, but they do eventually bloom. Fortunately, they don't seem to be so out of control either, I am sure the winters and shorter summers keep them in check to an extent as well. Mine are planted in thick, wet clay like soil amongst a rock wall, in between two houses, so they only get direct sunlight in the middle of the day. I just planted one last year at a lake house half way between Madison, WI and La Crosse, WI and it is growing fast and doing great-there it has full sun and sandy/rocky soils, so we shall see how many years it takes to flower there.

My experiences with yucca (I forgot there was another name for it) have been mostly positive. Truthfully, I have a love-hate relationship with it. I love the hardiness of it and the evergreen quality during the yucky OH winters. I also love the look of the flowers. I have learned to live with the negatives.
The big problem was not addressed in the article. It states the seeds grow on pods and can be saved for planting later. It doesn't say what happens if you don't remove the pods before they split on their own and drop thousands of seeds, which then grow and spread and spread and spread! One year I didn't get around to removing the stalk with the pods. The next spring I noticed what looked like blades of grass growing all over the bed where the yucca clump was. Eventually... read more, the light dawned!! It was baby yuccas from the seeds. YIKES! Fortunately, the roots hadn't gone deep yet and I was able to pull or dig up most of them to avoid being overcome with yuccas. The article also doesn't tell you that once a plant blooms, it dies. It should be removed from the still-living clump the next spring or whenever it dries up enough to break off.
Anyone who has seen yuccas grow shouldn't be surprised that they grow in clumps as the above poster was. The root babies are the best way to propagate, as they are well developed earlier than the seed babies. Use a shovel or other sharp instrument to separate the smaller clumps and stick them in the soil in any sunny space. Or give them away. Or pitch them, lol. I used to take unwanted ones to the plant booth at my parish festival. Now that the festival has been discontinued, I take them to my garden club's annual plant sale.
Leave some babies on the original clump to bloom later. Most of mine bloom in 3 yrs. I have 3 areas here at home (Dayton OH) with large clumps and a row of them against the back of my lake house 60 miles N. of here. That bed is not in full sun all day, but the plants do well. The yucca is pollinated by the yucca moth, as opposed to bees.
Make absolutely sure you want a yucca before you plant it. It doesn't take long for the roots to go down to China and then you are stuck with yuccas forever.

I just thought this plant was native to Georgia, and other places where tropical plants grow easily. I have not tried any 'experiments' or anything with this plant. It has bloomed a few times, and I've lived in this location most of my life. (My childhood home). I can only guess that the people who long-ago lived here before us, put it here. It has one pup, and I did not try to re-locate it because the spiney leaves are very sharp and did not want to risk getting cut. These two plants are side-by-side to each other and are in front of the house. The flowers hang upside-down, are bell-shaped, and white/creamy for it's color. And, they also have a nice scent, although I had to be careful of the spiney leaves when I walked-up to it. I do not wish to move it because I like them where they are.... read more Oh, yes. The soil it is thriving in here in Central Georgia, is red, hard-as-a-brick clay, with sand-like soil for topsoil.

I rescued mine from the woods where a landscaper must have dumped it a few years ago (maybe 6 or 7). At the time I felt it was the closest thing I'd ever have to a palm tree. Adam's Needle Yuccas are relatively common in Northeast PA. They seem to take some effort to transplant and establish but after that they are here to stay. Last week I felt it was getting too big for the spot it was in and thought I would remove the suckers ,trim the dead parts (not an easy task), and try an experiment. I have been attempting hardy palms here for several years. 2 of the supposedly hardiest palms (Needle, Sabal Minor) sort of resemble yuccas at a distance. I thought I'd remove the lower leaves and all the lower suckers and it seems to have an 8 to 9 inch (roughly) trunk. I wish I would have thou... read moreght of this years ago. The blooms are attractive in August for 2-3 weeks, then the stalk has to be removed or it looks unsightly.
I also would recommend this for erosion control as it has thick roots. I also recommend this be out where it has room to spread.

You can often see them growing on hillsides along highways in rather large clusters. They don't seem to be picky about growing conditions; they only demand sufficient sunlight. We have quite a few growing wild on our property, and they seem to grow fine in the native clay soil. The large flower stalks are a bonus.

Easy to grow plant. You can plant them and forget about them. Mine only flowers once every 3-5 years though. Foliage does look nice all year long. Brush snow off them if you want to keep the foliage neater.

These are growing wild about 1/2 mile from here..they cover a hillside along the road..I'm going to have to go dig one up and bring it home..I just love it when they are in bloom...:-)

Many people grow these plants around where I live because of their evergreen, tropical looking foliage and their beautiful flowers. I have seen some that have escaped cultivation and are growing in weedy, vacant lots. We have three established clumps in our yard, and they are really pretty, especially in the winter, when everything else is brown and dead looking, and the summer (around June), when they put up 5 ft tall flower spikes. I have also planted some at the edge of a small stream through the woods behind our house in hopes that they can push out the garlic mustard, and even have bought one of the attractive varigated cultivars from a local nursery. I reccomend these to all cold-area gardeners to add a bit of the tropics to your yard.

They are also extremely droug... read moreht tolerant, and will grow in a wide range of soil conditions... Our ground is clay over limestone, and we have no problems growing them, and I've seen them growing wild in Western VA under pine trees (i.e. most likely acidic soil) growing on sandstone along I-81.

I'm editing this to add a few more observations: I noticed that someone posted a pic of a trunked specimin, and I've observed this myself. Several of my Y. filamentosa have formed 1 to 2 foot tall trunks, but unfortunately, that is usually the point at which that particular rosette flowers, after which it dies over the following year. Usually there are enough other rosettes coming up from the roots to make this less noticible, but don't get your hopes up for a permanent trunked plant like with other Yuccas...

Also, what one person said about the root survivability is also true: My grandmother (the original source of my plants) had a wall put in along the road in front of her house (mainly to stop people who are speeding around the turn from running into her house), and there was a Y. filamentosa clump that was behind this wall, and buried under about 5 feet of fill dirt. I was sure that was the end of the plant, but about a year later, this plant managed to push up a couple of rosettes through said 5 ft of fill dirt, and started blooming again about two or three years after that! Yeah, those who said that once you have it, you've got it for good weren't kidding.

My grandad had these growing by his drainage ditch for years in Indianapolis. I collected seeds and dug up some starts and now have my own patch of them in Alabama. My plants have tended to form clumps of plants instead of staying as one solitary plant. I would rather it just stay as one yucca plant. It is very difficult to remove them, so like another user stated, plant them where you want them to stay forever. And put them where you won't mind if they grow a few offsets. When my yuccas bloom, the leaf-footed bug (leptoglossus phyllopus) comes and breeds on the blooms, causing them to turn yucky and brown. My plants rarely go to seed I think because the bugs are eating the pods or blooms.

In SE Michigan - We had one of these in the garden and were advised to divide when we revamped our landscape. Hard to dig up - but once divided even grew faster and more prolific. In three years we have taken over 20 "pups" off of 3 plants. These are terrific for foundation plantings - a different look for those who are tired of the traditional evergreens.

Grow this plant where you want it to grow forever! Once started its near impossible to get rid of. Any little piece of tuber will make a new plant.I have dug it up and thought I had it all and the next thing you know its back again. I even had it come through landscape cloth and 3 ft of soil where I had put raised beds over where it was.

Super easy to grow tropical-looking plant. All that is required is adequate drainage and some sun. Once you have it, it is there for keeps! Tuber-like growths in the root area ensure the plant stays, regardless of whether the top is removed or not. All parts of the plant are usable: root tubers are edible, leaves can be woven as fiber, and the flowers are delicious to eat as well as to smell. Super-easy to grow from seed, there are many named cultivars that are variegated, and that have different color flowers. Very attractive to hummingbirds, butterflies and bees.
